Currently ifdtool only supports writing one file (-w) at a time. This looks verbose when generating u-boot.rom for x86 targets. This change allows at most 16 files to be written simultaneously.

Do you need the initialiser?

I don't think so. Will remove in v2.

Will fix.

How about WRITE_MAX?

Sure.
